Conclusions:

Relative density: 1.750 at 20 °C.

Executive summary:

Method

Relative density was determined by means of a pycnometer as per recommendations of OECD guideline 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.

Result

Relative density: 1.750 at 20 °C.

Description of key information
